Key Takeaway:
- The AVEDEV function in Excel calculates the average of the absolute deviations of data points from their mean, providing a measure of how spread out the data is from the average.
- The basic syntax for the AVEDEV function requires inputting the range of values for which you want to calculate the absolute deviations. The function can also be nested with other Excel functions for more advanced calculations.
- The AVEDEV function’s advanced usage includes using arrays to calculate the absolute deviations for multiple ranges of data simultaneously, and comparing its results with other similar functions like STDEV and MAD. Understanding these nuances is important for making accurate and relevant calculations.

Basic syntax of AVEDEV function
Want to know the fundamentals of AVEDEV? Here’s a breakdown. Input your data, then calculate. Master this function in Excel and enhance your data analysis talents!
Explanation of how to input data for AVEDEV function
The AVEDEV function is widely used in Excel for calculating the absolute average deviation of a given set of data points. Here’s how to input data for this function:
- Select the cell where you would like to display the result.
- Type “
=AVEDEV(” into the cell, without the quotes. - Select the range of cells that contains your data points
- Enter a closing parenthesis
- Hit ENTER to generate your result.
It is important to note that AVEDEV works by taking into account all data points, including any outliers and negative values. Therefore, it may not be suitable for certain types of analysis. In some cases, other measures such as standard deviation or variance may be more appropriate alternatives.
A true fact is that Microsoft Excel was first released in 1985 and has since become one of the most widely used computer programs in modern workplaces.
Get ready for some statistical fun with AVEDEV – because calculating the average deviation has never been this exciting!
Example calculation using AVEDEV function
The AVEDEV function in Excel is a valuable tool for calculating the average deviation of a dataset. By subtracting each value from the mean, it calculates the absolute difference and finds out the average of all those differences. This can help in understanding how much variation exists within a dataset.
For instance, assume that you have data points representing the weekly sales of a product over five weeks. By applying AVEDEV on these values, you can determine how much the sales varied during these weeks.
It’s important to note that AVEDEV takes into account only numeric data and ignores empty cells or non-numeric values. Moreover, it does not take into account any outliers present in the dataset.
Pro Tip: Make sure to select an appropriate range while using AVEDEV as selecting too large or small ranges can result in inaccurate results.

Explanation of using arrays with AVEDEV function
The AVEDEV function in Excel can handle multiple data values at once using arrays. The array can be created manually or by referencing a range of cells. The function’s result is the average of the absolute differences between each value and the average of all values in the array. This use of arrays with AVEDEV makes it an efficient way of calculating variation for large sets of numbers.
To use arrays with AVEDEV, simply select the range of cells that contain your data points and input them into the formula. Alternatively, create an array manually by typing out all your values separated by commas within curly brackets {}.
It’s important to note that each array must be consistent in size and orientation for AVEDEV to work correctly. Also, since this function calculates deviation based on absolute differences, negative values will not offset positive ones in the final calculation.
Pro tip: Use Ctrl+Shift+Enter after typing out your array formula to confirm it as an array formula. Excel will surround it with curly braces {} if entered correctly.
Other similar functions may try to compete, but AVEDEV knows how to deviate from the norm.
Comparison with other similar functions
For a comprehensive understanding of AVEDEV function, it’s essential to compare it with other similar functions.
Here is a comparison table for AVEDEV with its similar functions:
| Function | Purpose | Formula |
|---|---|---|
| AVERAGE | Calculates the arithmetic mean of selected cells | =AVERAGE(number1,[number2],…) |
| MEDIAN | Returns the median of selected cells | =MEDIAN(number1,[number2],…) |
| STDEV.P | Estimates the standard deviation based on a sample | =STDEV.P(number1,[number2],…) |
| STDEV.S | Calculates the standard deviation based on a sample | =STDEV.S(number1,[number2],…) |
| AVEDEV | Calculates average of the absolute deviations | {=AVERAGE(ABS(AVERAGE(range)-range))} |
One unique detail about AVEDEV is that it considers all deviations from mean as positive and averages them, unlike STDEVP or STDEV, which squares each deviation before averaging them.
Understandably, not everyone can memorize complex Excel formulae. That’s why anyone who wants to master Excel should consider learning this powerful lesson.
Don’t get left behind by skimping on your understanding of advanced Excel tools like AVEDEV. Invest in boosting your Excel skills now to reach new heights in your career!

Practical applications of AVEDEV function
Practical Use of AVEDEV Formula for Data Analysis
AVEDEV formula finds the average deviation of a data set from its mean. This function is used by data analysts to measure the variability and dispersion of a set of data.
Below is a table that illustrates the practical use of AVEDEV function in data analysis. The table shows the deviation of each data point from the mean and then calculates the average deviation using the AVEDEV formula.
| Data Set | Deviation from Mean |
|---|---|
| 2 | -3.5 |
| 3 | -2.5 |
| 4 | -1.5 |
| 5 | -0.5 |
| 6 | 0.5 |
| 7 | 1.5 |
| 8 | 2.5 |
| 9 | 3.5 |
| Average Deviation | 2.5 |
It is worth noting that the AVEDEV function is particularly useful when dealing with large data sets and calculating the degree of variation.
One example of using the AVEDEV formula in real-life is calculating the volatility of stocks. The daily percentage changes in a stock’s price are calculated, and then the AVEDEV formula is used to determine the average deviation from its mean. This provides investors with insight into the risk associated with a particular stock.
